This practice note is one of two notes summarising the European Commission's consultation proposals to amend the requirements of the Markets in Financial Instruments Directive (2004/39/EC) and its implementing legislation, which were published in October 2010 following the Commission's review of the effectiveness of the Directive.

This note focuses specifically on the proposals that will impact on market structure and the way those markets, and those operating within them, function. It includes proposals to enhance requirements relating to the disclosure of trade transparency data, transaction reporting, the trading of derivatives on organised venues, oversight of derivatives trading and commodity derivative markets.
